[avr-gcc-list] C++/ATmega128 support for gcc-3.0.3 |

Hi All,
Attached is a patch for gcc-3.0.3 with all the ATmeg128 stuff in it and
the C++ stuff in it.
The destructor function run the destructors in the wrong direction, does
anyone have any ideas on how to fix it in libgcc.S? would anyone ever
use the destructors on an embedded system?
Can we get this into gcc-3.0.4 which is due to released 15 Feb?
Regards,
